[Qemu-devel] [Bug 1828272] Re: 4.0 breaks keyboard autorepeat in guests with xserver

[Frederick Metzengerstein]

** Description changed:

  Description:
  In a linux/bsd guest within X, pressing and holding a key for a short time 
causes an endless repeat of that key in the guest. The release of the key gets 
ignored.
  Example 1: pressing and holding 'a' for a few seconds results in typing of 
'aaaaaaaaaaaa...' endlessly.
  Example 2: pressing and holding 'Backspace' for a few seconds results in 
deleting all your previously typed text.
  
  It doesn't happen within a VT in the guest. It also doesn't happen with
  guests that run windows, reactos or haiku for example.
  
  The problem goes away, when disabling xorgs autorepeat function via "xset -r" 
in the host.
  Normally, this setting should not have any effect on the guest, since it has 
it's own autorepeat setting. So there is some conflict here.
  
  Steps to reproduce:
  Start any linux/bsd guest system with xserver, open a terminal, press and 
hold a key for a short time: Look how it gets typed endlessly (Try a few times 
if it doesn't happen immediately).
  The easiest way is to run a linux live cd, like this (Link to example iso 
:http://download.grml.org/grml64-full_2018.12.iso)
- $ qemu-system-x86_64 -enable-kvm -m 512 -boot d -cdrom grml64-full_2018.12.iso
+ $ qemu-system-x86_64 -enable-kvm -m 512 -net none -boot d -cdrom
